01x03 - The Birth of The Empire

Post by bunniefuu »

NARRATOR: A noble prince

reduced to poverty as a boy,

has risen above his brutal

childhood to become

a brilliant leader on

the Mongolian plains.

He is now the fearsome ruler

known as Chinggis Khan.

JOHN: What gave his followers

the idea that he was greater

than a mere conqueror was the

fact that he was so successful.

NARRATOR: He has crushed

foes, subdued rival houses,

and clawed back everything

his family lost.

PROF SNEATH: He achieves

a lot diplomatically,

which is a side to his career

that can easily be overlooked.

NARRATOR: Now, at

the age of 44,

he is the undisputed ruler

of the Mongolian people,

but he stands at the brink

of something far greater

with an insatiable hunger for

power, his eyes are set

on the world beyond Mongolia.

DR MAY: The world irrevocably

changed with his actions.

NARRATOR: Chinggis Khan's

ambition knows no bounds,

and soon the world will

learn the cost of standing

in his way.

PROF SNEATH: 1206, this is the

huge assembly, the Kurultai.

There would have been a lot of

ritual, great deal of luxury.

There would have been

power and pomp on display.

There are all the major Royals,

members of Chinggis Khan's

own family, are there.

DR MAY: You're gathering huge

numbers of people and livestock.

The Kurultai is where

they make major decisions.

DR FAVEREAU: Decision

concerning w*r,

decision concerning peace,

decision concerning

big trade treaties.

DR MAY: One most practical

reason for Kurultai is

to choose a new Khan.

DR FAVEREAU: When you become

a famous, important ruler,

you show it to the world.

You make it official

by taking a title.

Chinggis Khan is a title that

means also that something new

is going to happen under

this new ruler is sitting

on a very deep heritage, but

he is already planning to do

something new,

something bigger.

He wants to go higher

than his predecessors,

and he's able to break

tradition, and that's what,

exactly what he's

going to do.

Actually, this is the beginning

of a completely new story.

NARRATOR: It is a story

told in the legendary book,

The Secret History

of the Mongols,

a new translation helps

challenge long held beliefs

and myths about Chinggis Khan,

offering a new perspective

on his legacy and people.

PROF SNEATH: Chinggis Khan

is seen now in Mongolia as

the founder of the nation,

the father who created

the Mongolian people and

the world-famous conqueror.

That being said,

there's a difference

of opinion about him.

Some people are particularly

fascinated by the glory

of that Imperial age.

Others see him as part of a

conquest dynasty that did

invade and attack

its neighbors.

The idea that the Mongols were

barbarians, that's all nonsense.

We know these are highly

sophisticated political

formations, just as complex

and sophisticated

and as hierarchical as the

dynasties around them.

So, it's another very

sophisticated political

formation, just as other

kingdoms on the Eurasian

continent were.

NARRATOR: Central to

Chinggis Khan's vision

is the unification of the

people of the Mongolian plains

under a single banner,

loyal only to him.

DR MAY: He wants to have

one single Mongol people.

There's only going to be

one group on the steppe.

Everyone is now a Mongol.

This is why the Mongols

still exist.

Is because of this

moment in 1206,

Chinggis Khan has agreed there

will only be the Mongols.

NARRATOR: To achieve this goal,

Chinggis Khan reorganizes

the military structure

of his new realm,

adapting and refining

a military system

that strengthens his command.

PROF SNEATH: This was a

really ancient system

for administration that

dates back to at least

the second century BCE,

you can see that Chinggis

Khan did revamp it.

It divides up subject that

is, commoner households

into units of 10, fitted into

units of 100 those into units

of 1000 and those into

units of a nominal 10,000

he declares exactly which of

these 1000 household units

are authorized and

supported, and exactly who

is the hereditary Noble

who will rule over it.

He could designate members

of his own royal family

or his most important

supporters as rulers

of these 10,000

or Tumen units.

NARRATOR: Chinggis Khan

also knows he must protect

his position as leader as

one's warring households

come together under

his command.

DR MAY: This is where

the Empire really comes

into focus. He realizes he's

his single ruler of the step.

And he also needs to try to

get beyond the old system

that allowed for all the feuds,

all the fighting that have

taken place throughout

his lifetime.

He does not want

to return to that.

My sense of this is that he

does not completely trust

all of his relatives.

He is very focused on loyalty.

PROF SNEATH: Chinggis Khan has

inserted himself at the top

of an existing hierarchy

of commoners and nobles.

What was new was Chinggis

Khan's new reorganization

of the existing divisions of

power, the kingdoms within

that he had reused, absorbed

and replaced with his own

newly centralized

Imperial formation.

DR MAY: There'll be multiple

layers of authority.

He'll have his relatives, his

sons, ruling certain areas,

but he also has commanders.

They're ultimately

Chinggis Khan's men.

They ultimately

report back to him,

so they serve as a system of

checks and balances against

his relatives. Should

they ever have

some ambition to

threaten his power.

NARRATOR: The position of ruler

comes with unique dangers

and threats, so Chinggis

Khan prepares for challenges

to his authority.

JOHN: Very wisely preempts

any possible disloyalty

by creating a bodyguard.

It's called Keshig.

DR MAY: The Keshig consisted

of a total of 1100 men.

This included guards for the

daytime, included night guards,

included a special regiment

that rode with him into battle.

But in 1206, he increases

the size to 10,000.

He orders all of his commanders

to send the son to them,

and they would assemble

the bodyguard out of this.

Now this will serve

as a hostage.

It helps guarantee

good behavior.

If you misbehave, we could

possibly k*ll your son,

or if you misbehave,

we can k*ll you,

and we have someone here that

we can replace you with.

And these guys will

be great fighters.

They'll be great warriors.

So, it serves not

only a bodyguard,

but also a military academy,

an intelligence agency,

and it's a finishing

school for diplomats,

for governors to learn how to

rule on behalf of the Khan,

to understand the wishes.

NARRATOR: Genghis Khan's

reforms of the nobility

and a Kesh bodyguard make

him more powerful than ever,

but he will face untold

enemies, both from beyond

Mongolia's borders and

from closer to home.

After the death of

Chinggis Khan's father,

his mother remarried, and

this new branch of family

would soon ignite unrest.

PROF SNEATH: Chinggis Khan's

stepfather had seven sons,

and the middle one was

called K kecu Teb Tenggeri.

K kecu was his name, and Teb

Tenggeri was a title he had,

which means something

like most heavenly.

Now it seems that he was

a really powerful Shaman.

NARRATOR: The ancient faith

of the steppe rulers

was a shamanistic devotion to

Tengri, the eternal blue sky,

who controlled the

fate of the world.

DR FAVEREAU: At the

time of Genghis Khan,

they did have rituals and

believed in spirits of Nature,

trees, mountains,

rivers, lakes.

They are also ancestors.

In every important family,

people gather to celebrate

the family ancestors.

This is a very rich

set of beliefs.

PROF SNEATH: We find that

a lot of the declarations

of the spiritual and religious

refer to an overarching

heavenly power that created

destinies that favored

some rulers over others, and

that was used extensively

to justify Chinggis Khan's

claim to ultimate power.

So certainly, shamans

were important

in the Mongolian court.

DR FAVEREAU: Chinggis Khan

decided religious elites

need to be respected.

They also need to be

loyal to the power;

also, they need to stay away

and not decide for the Emperor.

That's also something

that you can see clearly

from 1206 onwards.

PROF SNEATH: At this stage, it

seems as if K kecu Teb Tenggeri

and his other brothers

become increasingly

arrogant and proud.

They seem to throw

their weight around.

A rivalry emerges.

Teb Tenggeri has started to

suggest that it's actually

Chinggis Khan's brother

Qasar, who might be destined

by Heaven to rule this

is a real threat

to Chinggis Khan himself.

NARRATOR: Teb Tenggeri's

poisonous rumors are so

persuasive that Chinggis

Khan grows suspicious

of his own brother until

their mother intervenes.

DR DASHDONDOG: Then mother

reprimanded Chinggis Khan

that you were just from the

same womb, same brotherhood.

You can't be rival

to each other.

You have to be

friendly to each other.

PROF SNEATH: Chinggis Khan

finds this coming to a head

when his younger brother

comes into his tent saying

that he's been beaten up by

Teb Tenggeri and his brothers

and begging Chinggis Khan

to do something about it.

NARRATOR: Chinggis Khan is slow

to move against Teb Tenggeri

until his wife Börte

urges decisive action,

warning that the shaman is

too dangerous to ignore.

PROF SNEATH: In

the secret history,

we get a lot of

accounts of women,

particularly the royal women,

giving advice and guiding

the prime male characters,

Chinggis Khan is often

given advice by his wife,

Börte and his mother,

Hö'elün.

Key decisions get made

because of good advice

from one of Chinggis

Khan's female relatives,

or his wife

NARRATOR: With Börte

urging him on,

Chinggis Khan devises

a plan of action.

PROF SNEATH: The solution

is they invite all of the

brothers, including Teb

Tenggeri to meet Chinggis Khan.

In the middle of that

meeting, he sort of grabs him

and pulls Teb Tenggeri

outside, where Chinggis Khan

has got three

wrestlers stationed.

When they get Teb

Tenggeri outside,

they pounce on him

and they k*ll him.

DR DASHDONDOG: They broke

Teb Tenggeri's spine.

NARRATOR: Teb Tenggeri

has been eliminated.

With this merciless act.

Chinggis Khan has quashed

internal descent.

But far more dangerous enemies

await beyond the steppe

ready to challenge his power.

With his kingdom reordered

and the people of the Eastern

steppe unified under his

command, Chinggis Khan's

wealth and power surges,

but his ambition

is far from satisfied.

He wants more and plans to take

it from a wealthy neighbor.

South of Mongolia is the

Empire of the Xi Xia,

ruled by people

known as the Tangut.

DR MAY: The Tangut were a

Tibetan Burmese people

who rule this region in

what is now Gansu Ningxia,

provinces of modern

day China.

The Tangut were both the

rulers and the nobility,

but also a nomadic people.

The Mongols had long

relations with the Tangut.

What the Tangut thought of

the rise of Chinggis Khan?

They couldn't have been

too happy about it.

In 1209, the Mongols invaded.

What he wants to do at this

point is basically nullify

the Tangut as a threat

to the Mongol state

that he's just created.

NARRATOR: As they head into

battle against the Tangut,

Chinggis Khan employs

an ancient maneuver,

the feigned retreat.

DR MAY: This is a

common step tactic.

Chinggis Khan does not

invent the feigned retreat.

It's been used for

1000s of years.

What matters is how

well you execute it.

The Mongols have trained

they're able to pull off

a feigned retreat.

So it is perfect.

They sell the retreats like

they are fleeing for their

lives, that they're

terrified of the Tangut.

This lures them out into a

place where the Mongols

have already designated as

this is a spot where we're

going to annihilate you,

but then you pull back.

It's a trap.

PROF SNEATH: One of the

ancient skills of the horse

Archer was the ability to ride

their horse, but also to turn

in the saddle and sh**t

backwards over the rump

of their steed.

It means that the horse

Archer can ride away

from their opponents.

If you are on a whiffed

steed, you can always outpace

the person chasing you,

but at the same time,

you can sh**t back at them,

which means that you can

sh**t at your enemies

without being in any

particular danger yourself.

This was a tactic used

by lots of steppe armies,

but the Mongols certainly used

it to really good effect.

NARRATOR: Coupled with

the feigned retreat,

Chinggis Khan uses another

devastating tactic

to eliminate large groups

in quick succession.

DR MAY: They used

arrow showers.

Down on a line of soldiers

trying to k*ll that entire area.

For the know it, the Tangut

have lost large portions

of their army.

NARRATOR: After success

on the b*ttlefield.

Chinggis Khan's forces marched

toward the Tangut stronghold,

prepared to stop at nothing

in their quest for victory.

DR MAY: Now the Mongols

are approaching Zhongxing.

This is the capital of Xi Xia.

They blockade it.

Someone gets the bright idea

of we have a river here.

Why don't we dam it

up and flood the city.

They don't have the engineering

skills to make a dam

that is really going

to be stable.

They do successfully

flood the city,

however, the dam breaks,

and they also flood

their own camp and

almost drown themselves.

But what this effort does is

demonstrate to the ruler

of Xi Xia that the Mongols

are a real danger.

and they're not just

going to go away.

We should submit.

And so they do.

And they offer gold.

They offer furs,

Falcons.

Also the ruler gives one of

his daughters to Chinggis Khan

as a wife. So now we have

a marriage alliance.

PROF SNEATH: in this case, I

think the implication is that

by giving the Princess The

Tangut ruler of the Xi Xia,

was showing that he

accepted the overlordship

of Chinggis Khan and showed

his loyalty to Chinggis Khan,

it was a way of cementing

a political arrangement

which acknowledged Genghis

Khan's supremacy

NARRATOR: To promote

peace and prosperity.

The gifting of wives is a

common diplomatic practice.

PROF SNEATH: These kinds

of diplomatic marriages

were obviously really

important features of

courtly politics at the time.

There was lots of interest

in having additional wives

for the emperor, so that you

would get another embassy.

The kin spoke of the new

queen would have access

to the internal

decision-making processes

and the ear of the emperor

through their kins, women

who had married into

the Imperial dynasty.

Chinggis Khan must have

had a lot of queens.

Many of them were useful,

diplomatic and political

marriages, which made sense

in terms of the dynasty,

as well as possibly his

own personal lifestyle.

NARRATOR: With his

numerous wives, concerts

and concubines, Chinggis

Khan may have fathered

many children beyond those

born to his primary wife,

Borte, fueling speculation

that millions today can trace

their lineage back to

the great conqueror.

DR MAY: Someone did a study

of DNA in the late 1990s.

It showed that male chromosomes

of a singular person were

common in a certain area that

fit in the Mongol Empire.

So naturally, everyone

assumes it's Chinggis Khan,

maybe, but maybe not.

It's an intriguing idea.

Who wouldn't want to be able

to make that kind of a claim

that you're a descendant from

someone of that magnitude.

NARRATOR: Chinggis Khan

has brought the Tangut

to their knees, and they have

paid tribute to spare

themselves from his wrath,

yet they are just one of many

enemies bordering his kingdom,

and new threats

will soon emerge.

Beyond his foreign conquests,

Chinggis Khan has tightened

his grip within his own land,

bringing any remaining local

rulers under his control.

PROF SNEATH: Chinggis Khan

finishes off his old enemies,

the Merkit.

He finishes off the

Naiman to the west,

and he makes some

diplomatic conquests.

The Uyghur, which were

originally a very powerful

Turkic dynasty, swear

fealty to Chinggis Khan.

They can see the way

the winds blowing.

They can spot the up and

coming power in the region.

NARRATOR: to manage

his expanding empire.

Chinggis Khan delegates

power to his four heirs.

PROF SNEATH: Chinggis Khan

was going to use his sons

as core commanders to lead

his armies on the various

different campaigns.

The Empire is getting

pretty big now,

Chinggis himself

can't be everywhere.

He wants to make sure that all

of his sons have some stake

in the new empire

that he's building,

whilst beginning to think

about what other big prizes

there might be.

NARRATOR: Chinggis Khan's

dominance soon draws

the attention of another

neighboring Empire.

PROF SNEATH: The local

superpower for a long time

was the Jin.

The emerging Jin formed this

really powerful and wealthy

empire in the northern

part of China,

and they were the sort of major

power players in that region.

NARRATOR: Chinggis Khan had

spent time in the employ

of the Jin when still

a young prince.

Although Chinggis

Khan is now ruler,

the Jin Emperor still expects

him to bow to their vast power.

DR MAY: In early 1211, an envoy

from the Jin Empire arrived.

From this envoy, he learns

that the old Emperor is dead

and the new guy is someone

that Chinggis Khan

does not have any

respect for.

Chinggis Khan listens and

he spits in the direction

of the Jin empire

and rides away.

He's not taking orders from

the Jin Empire anymore.

PROF SNEATH: Chinggis Khan

is finally in a position

where he's powerful enough to

consider taking on the Jin.

NARRATOR: Before attacking the

Jin, the Mongolians prepare,

both physically

and spiritually.

DR MAY: Chinggis Khan goes up

to the mountains and prays

to Tengri and seek His favor.

They'll definitely look for

divine help wherever they can.

NARRATOR: Chinggis Khan also

summons his trusted generals

and military leaders,

seeking their counsel

on battle strategies.

DR MAY: While he

demands loyalty,

he does not want yes men.

He wants people to point out

that might not be a good idea,

he may not be happy about it,

but he's going to listen

to it and consider it.

He always listens

to his commanders,

particularly those

who rose up with him,

working out what would

be the best approach.

How can we improve how we

fight so we don't make

the same mistakes.

We got to move an army from

here in central Mongolia

to the Jin empire.

We got to cross the

open steppe.

We got to go across bounds.

We got to cross the

Gobi Desert.

What does that require?

They have to figure

out the logistics.

Ultimately, he will

make the final decision.

He knows what the

Jin are capable.

They have the army

of roughly 600,000

which easily is five times

greater than the Mongol army.

PROF SNEATH: It's a

really big step to take

on this very formidable

dynasty.

But Chinggis Khan is finally

powerful enough to do it.

DR MAY: The Jin are facing an

enemy that they think they know.

They haven't realized that

things on the steppe

have changed.

These are not the Mongols

of the 12th century.

This is a whole new power

organized for warfare.

PROF SNEATH: Chinggis Khan

advances into Jin territory.

He invades in 1211,

the way the Jin had layered

their defense is

they had a zone of clients

who would be a buffer zone

between them and the

possible steppe powers

like Chinggis Khan.

These either defeated or some of

them recruited by Chinggis Khan.

A common narrative was that

the Mongols sort of kidnapped

engineers and other skilled

people and forced them

to fight in their armies.

NARRATOR: Chinggis Khan

rides into battle against

his most formidable foe yet

he must rely on cunning

and sophisticated

maneuvers to overcome

their superior strength.

DR MAY: The Mongols

do something

a little bit unexpected.

They don't just invade

as one big army.

They split up, and they're

going all over the place,

pillaging and plundering.

The Mongols seem like

they're everywhere.

PROF SNEATH: So this

idea of maneuver,

of coordinating strikes

between different mobile

armies simultaneously to

rendezvous on targets.

DR MAY It's difficult for

the Jin to really grasp

how many soldiers that

Chinggis Khan really has.

the Mongol army, they could

field armies that were

more sophisticated as

well as more skillful.

In many cases, they

were outnumbered,

but they were usually

more maneuverable.

Like other steppe armies,

they were cavalry only.

This was a really

superb advantage,

because if you come from a

sedentary or agricultural

state, many of your troops

and soldiers are likely

to be infantry on foot.

That makes for a

very slow army.

In comparison, an army that's

composed completely of cavalry

can move faster, and that's

one enormous advantage.

He's perfected his art

of w*r, the tactics,

the strategies he wants to

use, and the Mongols

execute them brilliantly.

It's not that the

Jin are incapable.

They're just meeting

a superior foe.

PROF SNEATH: Jebe,

one of his generals,

advances and then does a

feigned retreat to sort of

draw out the Jin forces.

And as they come out,

these different units

follow one at a time.

He can then round on them

and sort of defeat them

one after the next.

DR MAY: Chinggis Khan was in

the Jin Empire for 10 years.

He knows how they think.

He knows how they operate.

PROF SNEATH: Typical use

of mobility and trickery

to defeat opponents that might

have been numerically superior.

DR MAY: They win a couple

very important victories

that completely demolish

the armies of the Jin.

Every time the Jin sent an

army out, the Mongols routed,

things on the

steppe have changed.

Chinggis Khan is not a

young, inexperienced guy.

He has begun to change the

art of w*r in the step.

NARRATOR: Chinggis Khan

drives deeper into the heart

of the Jin Empire, his

forces leaving a trail

of devastation as they ravage

village after village,

seizing anything of value.

Relentless in his

pursuit of victory,

Chinggis Khan targets the

Jin's center of power.

PROF SNEATH: Zhongdu was the

capital of the Jin empire.

It was enormously

well fortified.

It was miles and miles of

wall all the way around,

and also towers, even small

forts that were placed

at strategic points to

help defend the city.

So it was a really formidable

defensive obstacle

for the Mongols to besiege.

NARRATOR: As the

Mongol as*ault begins,

the Jin leadership is already

crumbling under internal

conflicts, weakening

their resistance.

DR MAY: We're beginning to

see some people change sides.

The Jin will go through

a number of emperors,

some Jin commanders,

they'll join the Mongols.

Sometimes because, well,

you can either join or die,

or they decide, these guys

actually seem to know

what they're doing,

let's join the winner.

NARRATOR: Chinggis Khan senses

the Jin's internal weakness

and presents them

with an ultimatum,

submit and pay tribute or

face complete destruction.

DR MAY: In 1214, the

Mongols make peace.

PROF SNEATH: They

come to terms.

They agree to a

big, huge tribute.

DR MAY: We get lots of treasure

We get lots of good stuff.

The new Jin Emperor will also

give Chinggis Khan a princess.

PROF SNEATH: And those are

the conditions under which

Chinggis Khan withdraws

his armies.

NARRATOR: Although Chinggis

Khan commands a smaller force.

He has compelled the Jin

to submit to his will.

He has been fighting

for three years,

and leaves with a new wife,

vast treasures and abundant

resources, but the Jin have not

seen the last of Chinggis Khan.

With tributes secured and

a peace treaty in place,

Chinggis Khan and his army

prepare to withdraw

from Jin territory.

DR MAY: They're not

necessarily trying

to conquer the Jin empire.

Their early actions in

the first few years

are very much to

secure the borders.

He wants to make sure that

it is safe from invasion

and from Jin meddling.

However, as the campaigns

go on, people have this

annoying tendency to either

flee, which means if you want

to get more plunder, you

have to keep going deeper

into the Jin empire, or

possibly even worse,

they surrender and

want you to rule them,

so you have to stay and

deal with these people.

So the Mongols will bring

in former Jin officials

that they feel that they

can trust and allows them

to be ruled as they were

used to being ruled.

We get another layer

of Mongol governance,

not only does he have his

relatives, his generals,

also the local administration.

NARRATOR: Although the

Jin Emperor has admitted

to the Mongol army, he

makes a reckless decision,

one that will prove costly.

DR MAY: The new emperor

decides to move from Zhongdu

to Kaifeng, which is 550

kilometers south southwest

of modern Beijing, so far

away from the Mongols.

Why does he do this?

Some people think

maybe disease.

There's a lot of death and

destruction in the area.

But the other thing is,

the Mongols have caused

so much damage in that area,

it is not a secure zone.

That's really not

where you feel safe.

Even if you have a peace

treaty, you have to be

a little bit nervous

about that. So he moves.

For Chinggis Khan, this is

seen as an act of betrayal.

We made peace.

You've just demonstrated

that you don't trust me.

So it's on.

NARRATOR: The Emperor's

ill-advised move provokes

the Mongols into launching

a second as*ault

on the Jin's capital,

Zhongdu.

DR MAY: The Mongols once

again invade Chinggis Khan

again has immense

emphasis on loyalty.

If you switch sides in

the middle of the battle,

most likely he's

going to execute you.

He doesn't have any

patience for that.

PROF SNEATH: The siege

of Zhongdu stretched on.

It wasn't over quickly.

It was a really formidable

defensive obstacle

for the Mongols to besiege.

DR MAY: It's an immense city.

What they do is they

leave detachments

round the city to

basically blockade it.

From Kaifeng, the Jin

emperor, authorizes attempts

to save the city, but the

Mongols will defeat these

as they come.

The Jin armies will have

archers, crossbow men,

giant crossbows, a contraption

that could sh**t a giant

crossbow bolt several 100

yards and neutralizing

anything it hits.

So for the Mongols to take

this they had to figure out

how to overcome all these

obstacles, eliminates threats

from the fortresses.

NARRATOR: Instead of

breaking through the city's

fortifications, the Mongols

choose a more ruthless strategy.

They will starve the

city into surrender.

PROF SNEATH: Siege warfare

in this age was a really

terrible ordeal for the

occupants of any city.

They were cut off

of stocks of food.

They begin to starve.

DR MAY: It is not uncommon for

people in Zhongdu late at night.

You might get nabbed

in the alley

and become someone's dinner.

Cannibalism is very real in

Zhongdu in the later months

of the siege.

the siege lasts no more than

a year before it finally

surrenders.

People are starving.

They can't put up a

further resistance.

The city falls.

PROF SNEATH: Although they now

control a lot of Jin territory

and have displaced the Jin

Dynasty itself that has had

to relocate and flee, it is not

as if the fighting was over.

Chinggis himself left one of

his best generals, Muqali,

who for many years continued

the campaign against the Jin

there was an ongoing

rolling campaign of mop up

that was masterminded

by Muqali.

And one of the reasons

why he was so respected

in the Chinggis core was

because it was recognized

that this was an enormous

effort that he undertook,

that eventually bore fruit

when the Mongols eventually

came to control the whole of

the Northern Chinese plain.

DR MAY: The Jin Empire

will hold out until 1234,

it does not go away easily.

NARRATOR: Although it will

take many years for the Jin

to be fully defeated.

The Mongolians are building

a fearsome reputation

on the b*ttlefield,

and they will ensure

that their brutal actions

become legendary.

DR MAY: In many places, they

would wipe out everybody,

but maybe a handful

of people or one guy,

and that one guy would

always tell the story,

and the story was

always scary.

They k*lled everyone. They

came back five days later,

they k*lled even more people

who came out of the rubble.

So the fear is building.

There's one story told by a

Persian chronicler Juvayni

that 60,000 virgins leapt off

the walls to their death,

rather than be taken

by the Mongols.

Another story tells of a caravan

coming from Central Asia.

It was sent by the

Kharazmshah to find out

what's going on in China.

And as they're approaching,

they see these white mountains.

They think they're

covered with snow,

but then they realize

they're just piles of bones

from the Mongol conquest

in northern China.

As a pro Zhang du the

road is getting slick,

and it seems wet, and they

discover it's from human fat

that's been melted.

You get this sense of

overwhelming dread about

the Mongol invasions.

The Mongols are not

simply another army.

They're a force of nature.

They are the apocalypse

incarnate.

NARRATOR: Chinggis Khan,

having fearlessly battled

the once mighty Jin empire,

now turns his gaze west

to empires filled

with untold riches.

These lands, unaware of

the approaching storm,

will soon feel the

devastation

of his relentless force.
